Definitions
- the present invention relates to a method and a device for rapidly warming up and thermally regulating the lubricating oil of an internal combustion engine. It applies to internal combustion engines in which cooling is ensured by the circulation of a fluid in suitably arranged conduits in the region of the combustion chamber.
- a cooling fluid having a high specific heat and a low viscosity such as a water-additives mixture
- This cooling fluid pressurized by a pump circulates in an annular chamber whose thickness, which varies according to the means of production such as sand cores or molding parts of steel molds, reaches several millimeters.
- This thickness given to the blade of the cooling fluid proves to be superabundant because only a surface layer, being in contact with the walls of the cooling chamber of the jacket or of the cylinder, is used for the extraction of calories.
- the flow rate of the cooling fluid necessary for a suitable heat exchange, implies a particularly costly flow.
- the present invention aims to exploit the aforementioned property specific to the surface layers and for this purpose proposes to use the so-called external wall of the cooling chamber, opposite to the liners or to that forming the cylinders, for transmitting or removing calories from the engine lubricating oil by making the best use of its calorific capacities.
- This lubricating oil can thus be quickly brought to temperature and its temperature can be regulated by heat exchange with the engine coolant.
- the process for rapidly warming up and regulating the temperature of the lubricating oil for an internal combustion engine of the type cooled by a coolant with high specific heat and low viscosity, circulating around the cylinders or liners of this engine consists of a heat exchange between this coolant and this lubricating oil at the upper zones of these cylinders or of these liners, this oil being capable of capturing calories coming from the cylinder head from this engine to transfer them to this coolant.
- This heat exchange makes it possible to dissipate the heat coming from the combustion chamber on the one hand, and from the cylinder head on the other hand, in the cooling fluid.
- the engine lubricating oil will be used to capture calories from the cylinder head, the temperatures of which can greatly exceed those of the cylinders or liners. This results in a very rapid rise in temperature of this oil associated with regulation of the temperature of this oil by heat exchange with the coolant.
- a device for implementing the aforementioned method comprises, around the cylinders or liners, a first annular chamber in which circulates a coolant from the engine and a second annular chamber, concentric with the previous one , in which the engine lubricating oil circulates, this second chamber partially or totally surrounding the first so as to form therewith a heat exchanger.
- the engine shown in the single figure comprises a cylinder head 2, a cylinder block 4 and a casing 5.
- Each cylinder 6 of the block 4 receives a dry jacket 8 and possibly a removable wet jacket.
- the upper region of each cylinder 6 or jacket 8 is conventionally surrounded by a first chamber annular cooling 10 in which circulates a water-antifreeze mixture 12.
- This chamber has inner 9 and outer 11 walls.
- the engine lubrication circuit essentially and conventionally comprises a positive displacement pump 20, an oil pressure limiter 22, an oil filter 24 and a suction strainer 26.
- the outer wall 11 of the chamber 10 can therefore transmit or remove calories from the lubricating oil 18 which licks it.
- the fins 16 favor the heat transfer between the two annular chambers 10 and 14. As it is desirable to maintain the cylinder head 2 and the members which are attached thereto (valve seats, valves, spark plugs, etc.) at a compatible thermal level with good mechanical strength when hot, we will use this lubricating oil 18 to capture the calories from of this cylinder head 2, the temperatures of which may exceed those of the cylinders 6 or of the liners 8.
- this oil 18 When the engine is started cold, this oil 18 will be quickly brought to temperature, by loop circulation by means of a positive displacement pump and by heat exchange with the cylinder head 2. The temperature of this oil 18 can then be regulated by heat exchange at through the outer wall 11 of the water chamber 10.
- the minimum oil flow used for cooling the cylinder head 2 is a flow conditioned by the idling lubrication pressure of the hot engine.
- the maximum flow rate corresponds to that of the relief valve 22, used to limit the lubrication pressure to a minimum value required, in the conventional volumetric oil pump 20.
- the energy expended for circulating the lubricating oil 18 used for cooling the cylinder head 2 varies essentially as a function of the pressure drops in this cylinder head; however, these are largely compensated by the fact that the temperature rise of the oil is very rapid, that the temperature of the oil is then regulated, which makes it possible to use an oil of low viscosity.
- the heat exchange between the cooling fluid 12 and the lubricating oil 18 therefore makes it possible to significantly reduce the energy expenditure necessary to reach the optimum operating temperature of an internal combustion engine.
- the cooling fluid 12 while only passing through the water chamber 10 around the cylinders 6, captures the assembly there. calories from the engine.
- the pressure losses of the water cooling circuit are considerably reduced since the latter no longer concerns the cylinder head now cooled by the lubricating oil.
- the length and the flow rate of this circuit are then substantially halved and the cooling radiator can be optimized as a function of this flow rate and the temperature variation interval of the engine.
